Recently we found Paul Madary's blog post about digital signatures in a Univeral Application (UWP) with iText 7, and we wanted to share it. Paul gracefully agreed to let us do that, and as a bonus we upgraded the code to be usable out-of-the-box with iText 7.1.3. The only change needed is the method SignDocumentSignature.

A big thank you to our Q3 top contributors!

There are so many people that contribute information to us in order to help improve our code, products and projects. We want to make sure that our top contributors are being recognized for the help they give and that they know how much we appreciate them.

Add the parameter maven.test.skip=true or skipTests=true in the command line. The tests create plenty of PDF files (new documents) that need to be compared with reference PDF files (existing documents stored with the tests). Ghostscript is used to create images of those PDF files. These images are compared on a pixel basis to check if the new files have the same appearance of the reference files.

If you want to build iText with the tests, you need Ghostscript. If you want to build iText merely to get a jar, you can skip the tests and you don't need Ghostscript.
